Custom PO Forms

I have not found a way to customize the PO Form to include several standard aspects as noted below:
1. Selection list to Sites (If Sites had addresses associated with them)
2. Auto Generation of non-duplicate PO numbers as an options
3. Multiple approval Paths
4. Cost Center & GL Code information so Finance can use this module as well
5. Use of Roles where specific PO by department can be approved by that department approver
6. No Date stamp within the PO activity log for each step of the process (required for auditing) Wait, there would need to be a PO process activity log to collect this audit data first!
7. Workflow process editor to define the PO approval process.
8. Custom Form editor to create the PO form that is acceptable to Finance.
